UPDATE 18.12.2009: I've added sounds and music to the game. I've also changed number of battles. Thera are 7 enemy fleets now :). Enjoy. And thanks to You all for giving me ideas!
UPDATE 14.12.2009: Thanks for comments (You're first community, that I'm showing this game to). I've fixed bug that SilentOmega found, and I've added special function - by pressing SPACEBAR you can now cancel Your shoot (if it has no sense - You're sure, that it'll miss) - thanks to Ryuk456 for idea.
UPDATE 13.12.2009: (due to comments) You're totaly right - sounds will be next thing, that You'll have done in this game. Give me few days ;].
I've done everything by my own.
Just enjoy, and leave a comment, which I'll consider in developing and fixing bugs in this game :).
